Air humidity is one of the most important measurement parameters. Depending on the application, different performance requirements are made when it comes to a humidity meter. We offers an unbeatable diversity of instruments: from the simple humidity meter, via thermohygrometers and multifunction measuring instruments, through to the humidity data logger with software.
A humidity meter records the water vapour content of the air. The warmer the air, the more water vapour it can absorb before it becomes saturated and reaches maximum air humidity.
- Relative humidity is the most commonly measured value. It indicates the air humidity present in the room in relation to the maximum air humidity. It is given in "percent relative humidity" (% RH). This means for example that the comfort level range is between 30% RH and 65% RH.
- On the other hand, absolute air humidity indicates the quantity of water vapour in a sealed volume of 1 m³. It is expressed in grams per cubic meter (g/m³), for example to document the removal of humidity in drying processes.
- The dewpoint is also an element of air humidity. It indicates the temperature to which the air has to be cooled for condensation to occur. If the process temperature for instance falls below the dewpoint, condensate develops.
Material moisture meters are indispensable when it comes to determining moisture in buildings and timber and discovering the cause of moisture damage. Material moisture measurement is quick and easy to do nowadays, even for private users. A wide range of different instrument models and humidity probes enable non-destructive measurement in virtually all common materials and timber.
